Find Your Known Traveler Number: Global Entry, NEXUS, SENTRI

Your Known Traveler Number (KTN) for Global Entry, NEXUS or SENTRI is your 9-digit CBP PASSID. It is printed in the upper-left corner on the back of your card and shown in your account after you log in to ttp.dhs.gov. Below is how to find my known traveler number in three places, plus what to do if you have no working number because you are still waiting on an interview.

How to find my known traveler number (KTN) in 3 places

1. On the back of your card. Look at the upper-left corner of your Global Entry, NEXUS or SENTRI card. The 9-digit number there is the PASSID (TSA FAQ).
2. In your Trusted Traveler Programs account. Log in at ttp.dhs.gov. The Membership Number, also called the PASSID, is your KTN (TSA; The Points Guy).
3. In an airline profile. If you have already flown with the number, check the frequent-flyer profile for that airline. Chase and The Points Guy list this as a backup.

A PASSID is 9 digits and usually starts with 10, 13, 14, 15, 16, 50, 70, 80, 95, 98 or 99 (TSA FAQ; Capital One).

If you enrolled in TSA PreCheck on its own, you have a different number. TSA has its own KTN lookup for that. Keep it separate from a PASSID.

Forgot your KTN or lost your card?

Log in at ttp.dhs.gov and read the Membership Number, which is your PASSID and your KTN. You do not need the card in your hand to see it.

How to use it once you have it

To get PreCheck, enter the PASSID in the Known Traveler Number field of each reservation (TSA FAQ). The card in your wallet does not do this for you.

• Type only the number, with no extra text (Delta).
• Leave the Redress Number field alone (Delta).
• To add it after booking, open the trip on the airline's site or app and find the "Known Traveler Number" or "Secure Traveler" field. Then re-download your boarding pass so the PreCheck mark shows (The Points Guy).
• If you add it to a Delta profile, Delta says it syncs to existing trips within 36–48 hours.

If the number gets rejected or the mark is missing

First, check that your first, middle and last name, date of birth and gender match your TTP profile exactly (Delta; Upgraded Points). Second, if you booked through a third party, the KTN may not have reached the airline, so add it on the airline's own site.

No KTN yet? It is waiting on your interview

If you are conditionally approved but have not done your interview, you do not have a working KTN. Delta's FAQ says KTNs only become active after enrollment at an enrollment center. The interview is the step to move up.

After a successful interview, the 5-year membership starts right away. The PASSID works as a KTN even before the card arrives, and card delivery ranges from 7 days to 8 weeks (QueueCheck, citing TTP and CBP).

The numbers to keep in mind:

• The CBP fee is $120, non-refundable, for 5 years. It is the same for Global Entry, NEXUS and SENTRI.
• You must finish the interview within 730 days of conditional approval. After that the application is cancelled with no refund (QueueCheck, citing DHS).
• Most applicants without criminal history get membership in 4–6 months. Some take 12 months or more (QueueCheck). The full stage-by-stage timeline is in our turnaround time guide.

Worked example: counting the days

These numbers are made up to show the method. Your own dates will differ.

1. You are conditionally approved on day 0. Today is day 60.
2. Open Global Entry appointment availability. Your home center shows a next bookable date 140 days out. That puts the interview on day 200, and 530 of your 730 days remain (730 − 200).
3. Open Global Entry wait times and compare nearby centers. A center two hours away shows a next bookable date 45 days out. That is day 105, which is 95 days earlier, with 625 days left.
4. For NEXUS or SENTRI, use NEXUS wait times or SENTRI wait times.

The availability page shows each center's next bookable date (not whether a slot is open right now). Dates shift, so check again before you plan a trip around one.

Interview options that skip the calendar

You can also do the interview through Enrollment on Arrival or Enrollment on Departure at participating airports. Neither needs an enrollment center appointment. Check that your airport takes part before you count on it.

Renewing: your KTN stays the same

You can renew up to 1 year before your membership expires. If you file before expiration, your benefits continue for up to 24 months while CBP processes the renewal. Your KTN stays the same (QueueCheck). An interview may be required. Chase notes that many people start about 6 months ahead.

Hearing about an earlier interview slot

If your center's next bookable date is months out, you can still watch for a sooner one. GlobalEntryTexts texts you when a Global Entry, NEXUS or SENTRI interview appointment opens at the enrollment centers you choose. It costs $25, paid once, for 30 days of monitoring, and it is not a subscription. You can watch up to 3 centers in that window. You book the appointment yourself on ttp.dhs.gov.
